Physics Review Letters New 'molecular movie' reveals ultrafast chemistry in motion
Scientists for the first time tracked ultrafast structural changes, captured in quadrillionths-of-a-second steps, as ring-shaped gas molecules burst open and unraveled. Ring-shaped molecules are abundant in biochemistry and also form the basis for many drug compounds. The study points the way to a wide range of real-time X-ray studies of gas-based chemical reactions that are vital to biological processes.

Nature Communications Study finds a way to prevent fires in next-generation lithium batteries
In a study that could improve the safety of next-generation batteries, researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites -- 'fingers' of lithium that pierce the barrier between the battery's halves, causing it to short out, overheat and sometimes burst into flame.

Cell X-ray study may aid in designing better blood pressure drugs
An experiment at the Department of Energy's SLAC National Accelerator Laboratory has revealed in atomic detail how a hypertension drug binds to a cellular receptor that plays a key role in regulating blood pressure. The results could help scientists design new drugs that better control blood pressure while limiting side effects.

Nature Researchers hit milestone in accelerating particles with plasma
Scientists from the Department of Energy's SLAC National Accelerator Laboratory and the University of California, Los Angeles have shown that a promising technique for accelerating electrons on waves of plasma is efficient enough to power a new generation of shorter, more economical accelerators. This could greatly expand their use in areas such as medicine, national security, industry and high-energy physics research.

Nature Materials Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated.
The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.

Nature Communications Buckyballs and diamondoids join forces in tiny electronic gadget
Scientists have married two unconventional forms of carbon -- one shaped like a soccer ball, the other a tiny diamond -- to make a molecule that conducts electricity in only one direction. This tiny electronic component, known as a rectifier, could play a key role in shrinking chip components down to the size of molecules to enable faster, more powerful devices.

Science X-ray laser probes tiny quantum tornadoes in superfluid droplets
An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum 'tornadoes' inside microscopic droplets of supercooled liquid helium -- the first time this formation has been seen at such a tiny scale. The findings by an international research team provide new insight on the strange nanoscale traits of a so-called 'superfluid' state of liquid helium.

Science Uncertainty gives scientists new confidence in search for novel materials
Scientists at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have found a way to estimate uncertainties in computer calculations that are widely used to speed the search for new materials for industry, electronics, energy, drug design and a host of other applications. The technique, reported in the July 11 issue of Science, should quickly be adopted in studies that produce some 30,000 scientific papers per year.
The Department of Energy's Office of Science is the single largest supporter of basic research in the physical sciences in the United States and is working to address some of the most pressing challenges of our time.
